San Francisco Bay Bridge east span opens

After years of delays and cost overruns, the newly built US$6.4 billion eastern span of the San Francisco-Oakland Bay Bridge opened with few problems other than the traffic snarls that were common around the toll plaza of the old span. The single pylon suspension span replaces a structure that was damaged during the 1989 Loma Prieta earthquake. It is designed to withstand the strongest earthquake estimated by seismologists to occur at the site over a 1,500-year period.

After years of delays and cost overruns, the newly built US$6.4 billion eastern span of the San Francisco-Oakland Bay Bridge opened with few problems other than the traffic snarls that were common around the toll plaza of the old span.

The single pylon suspension span replaces a structure that was damaged during the 1989 Loma Prieta earthquake. It is designed to withstand the strongest earthquake estimated by seismologists to occur at the site over a 1,500-year period.

One of the busiest spans in the United States, the single-towered, 634 metre long self-anchored main span is more than twice the length of the previous record holders, Japan's Konohana Bridge and South Korea's Yeongjong Grand Bridge, according to the Structurae engineering database.

It has been completed six years behind schedule at five times over budget. It will be used by some 280,000 daily commuters.

The Jane Addams Memorial Tollway in Illinois, US is well on the way towards becoming a ‘smart traffic corridor’, taking full advantage of active traffic management (ATM or ‘managed lanes’) technology that originated in Europe. It is one of the first American toll roads to do so; preliminary work began in 2014 and will continue through to 2016.

Objections from local residents and the failure of the Turnpike to consider the alternative of all-electronic tolling (AET) led to the delay of a previous ten year plan in 2009 that set

The effects of climate change on the transport infrastructure have long been a cause of concern within the transportation sector - and not only on the structures themselves but also on the surrounding areas. This year, those concerns have become reality with landslides, structural collapses and surfacing issues impacting services across the wo
